About Q52.2

Q52.2 is the ICD-10-CM diagnosis code for congenital rectovaginal fistula. It belongs to category Q52 (other congenital malformations of female genitalia), block Q50-Q56 (congenital malformations of genital organs) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Q52 (other congenital malformations of female genitalia), Q52.2 is specifically for congenital rectovaginal fistula. Related codes cover congenital absence of vagina (Q52.0), doubling of vagina (Q52.1), Imperforate hymen (Q52.3), other congenital malformations of vagina (Q52.4), fusion of labia (Q52.5), congenital malformation of clitoris (Q52.6), other and unspecified congenital malformations of vulva (Q52.7), other specified congenital malformations of female genitalia (Q52.8) and 1 more.

Don't report Q52.2 together with the conditions in its Excludes1 note: cloaca (Q43.7).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 742 (Uterine and Adnexa Procedures for Non-Malignancy with CC/MCC, relative weight 1.8456), DRG 743 (Uterine and Adnexa Procedures for Non-Malignancy without CC/MCC, relative weight 1.2974), DRG 760 (Menstrual and Other Female Reproductive System Disorders with CC/MCC, relative weight 1.0129) and DRG 761 (Menstrual and Other Female Reproductive System Disorders without CC/MCC, relative weight 0.7041), in MDC 13 (Diseases and Disorders of the Female Reproductive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It is on the CMS list of diagnoses consistent only with female patients (the sex-conflict edit itself was retired in FY2025).

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 752.49 (other anomalies of cervix, vagina, and external female genitalia).
